10-5 = 0.00001
a 1 followed by 5 zeroes.

10^(-5) = 0.00001 = 1/100000
1,000,000,000,000,000,000
10th to the 5th power = (1/10) to the fifth power = (1/10)5 = (1/10)*(1/10)*(1/10)*(1/10)*(1/10) = 1/100,000 or 0.00001
Three and four tenths multiplied by ten to the fifth power
105 * 105 = 1010 which is 10 billion.
10 to the fifth power in scientific notation is expressed as 105
381.8 divided by 10 to the fifth power equals 0.003818
Nine to the fifth power looks like this: 95
10^5 or 100,000
For scientific notation, Ex is used, where x is the power of 10. Therefore, you could write your number as: 3.78E5
100,000
100,000
106
Write 750 then put 45 zeroes after it. That is why powers of ten are so convenient.
